//  The following specializations take into account the C++ standard
//  library components. There are a couple of issues that has to be
//  dealt with to enable lazy operator overloads for the standard
//  library classes.
//
//      *iostream (e.g. cout, cin, strstream/ stringstream) uses non-
//      canonical shift operator overloads where the lhs is taken in
//      by reference.
//
//      *I/O manipulators overloads for the RHS of the << and >>
//      operators.
//
//      *STL iterators can be objects that conform to pointer semantics.
//      Some operators need to be specialized for these.
//
//      *std::complex is given a rank (see rank class in operators.hpp)
